(a)
Interpretation:
Isoprene units in the given set of compounds need to be circled.
Concept introduction:
Terpenes are naturally occurring compounds which share a common feature. All terpenes are thought to be assembled from isoprene units having five carbon atoms. So the structure of terpenes has the carbon atoms in multiples of five only.
The isoprene units are identified by following few steps namely,
- Identify the number of isoprene units
- Look for methyl group
- Trial and error to find isoprene unit
To identify: the isoprene units in menthol
